Age categories can change from first year (Fy) to adult (Ad) for individuals between years, so each year is presented separately (13–14 sampling periods). Differences are considered significant when 95% CIs for effect sizes do not overlap with zero. Sample size (N) shows both total number of observations (No) and number of individuals (Ni), and effect size shows 95% CIs.
